Why does Team Render Server or Cinema 4D only see one Client when multiple clients are installed?

Problem:

TeamRender Server or Cinema 4D sees just one client, even though multiple clients should be available.

Cause:

Each client creates a unique ID upon first startup inside the preferences folder. If you clone an entire computer's data or partition, all clients will have the same ID, causing the server to recognize only one of them.

Solution:

After installing and updating the client, and before cloning, delete the preferences folder. You can find the folder through the preferences inside the program itself by using the "Open Preferences Folder..." button at the bottom.

Alternatively, you can copy the Cinema 4D/Team Render Clients installation folder to other machines instead of cloning entire computers or partitions.
